Humans can't build a real big ship until they understand the "Navi-Stokes equation"; you can't really invest until you understand a series of principles such as evolution theory, probability theory, and entropy; what human beings have to do , or what you have to do, is to understand these things. The real winners are those who stop and learn. When others say this is an opportunity, but I don't feel it at all, I don't follow others to do it for the first time, but lean over to understand: what is this, why is it an opportunity, why others are not, what it does Being recognized, why others say that.
